A little brain teaser...
 

There are three new houses being built on a street, luckily there are also three utility provider substations that the houses can be connected to. The situation looks thus:

Now draw a diagram of how to connect all three houses, independantly to all three utilities providers (i.e. one connection serves just one house).

There is just one rule: None of the proposed new connections may intersect (cross) each other. For instance if I draw straight lines between the water and houses to connect them I can't then draw straight lines from any of the remaining substations to the houses.

Good luck!

Can I draw not straight lines ?

They can be 'straight' but with 90 deg turns in them..........

That's easy then . . . . . isn't it ?

TD you went v quiet for a while . . . Guess you've got the job sorted out and can come out to play again ?

Yes, and move them around if you wish into different configurations.

Go on, draw it out ;).

Do you consider a house as an infinite point, or of a finite size?

(You know where I'm going with this ;) )

Re: A little brain teaser...
 

Ok, one of the houses will have to use their mobiles . . . . :)

And no, I have no idea where you are going . . .

Spoiler in white...

"If the houses are of finite size, you can run a cable underneath one of them without it crossing any other cable, so allowing you to make all the connections you need."

Re: A little brain teaser...
 

Yes, yes...or the sub-stations.
